Starting with 2021, Switzerland has set new directions for a sustainable future by adopting the climate strategy submitted to the UN Climate Change Secretariat. The country thereby enters the list of states that have developed such a long-term strategy for 2050, year in which Switzerland is expected to be a zero-emission economy. In order to align itself with these objectives, Switzerland is on course to transform its transport system, which must significantly reduce its emissions, with the shift of traffic to the railways being one of the best options. As a result, it has revised its 2050 strategy to be in line with the policy of eliminating the impact on the environment.
According to analyses, in 2018, GHG emissions in Switzerland amounted to 46.4 million tonnes of CO2, down 14% from 1990 levels, and in 2005 there was a downward trend, even though the population increased and although GHG per capita decreased from 1990 to 2018. In addition, with the air transport and shipping sector included, which are not part of the national and international assessment parameters, 2018 emissions amounted to 52.1 million tonnes of CO2, representing a 9% decrease compared to 1990 levels. Depending on the different areas, the reduction in emissions was mainly due to the building sector and especially to industry, and even more, agriculture. Transport has remained the sector with the largest share of emissions for a longer period than other sectors, and although the trend has been downward, emissions have been somewhat at the same level of 1990. Emissions from international air traffic have experienced an upward trend and account for 10% of Switzerland’s total emissions.
